Atlas of North American Exploration

I wondered if Edward Tufte or any of the rest of you have seen the
book The Atlas of North American Exploration by William
Goetzmann and Glyndwr Williams. I think it does a very effective
job of graphically and verbally presenting various historic
explorations throughout North America. I especially love the
1854 hand-colored lithograph (pp 168 – 169) done for the Great
Pacific Railroad survey. It is a sort of 3-D map showing a
panoramic view of the Rocky Mountains, and terrain that a
railroad could pass through.
